I see this posted about on the internet quite a bit, but cannot find the source. I've looked on RAVE and in the service/recall actions but cannot find it. Anyone know ?
From the workshop manual....
AFFECTED RANGE:
All Td5 derivatives within VIN ranges:
Discovery Series II (02 Model Year) 2A 736340 to 3A 793895
Defender (02 Model Year) 2A 622424 to 3A 647705
SUBJECT:
CYLINDER HEAD LOCATING DOWELS
Td5 engines fitted to vehicles in the above VIN range are fitted with plastic dowels to locate the cylinder head onto the cylinder block.
Land Rover Engineering has introduced steel locating dowels from the following VIN numbers:
Discovery Series II: 3A 793895
Defender: 3A 647705
INFORMATION:
If a cylinder head is removed from a vehicle in the above VIN range, the plastic dowels must be replaced with new specification steel dowels, which are now available from Land Rover Parts.
CAUTION:
Td5 derivatives prior to the above VIN ranges must not, under any
circumstances, be fitted with the new steel dowels. If steel dowels are fitted to earlier engines, cylinder head cracking may result.
